Beer in Belgium varies from pale lager to amber ales, lambic beers, Flemish red ales, sour brown ales, strong ales, and stouts. In 2018, there were approximately 304 active breweries in Belgium, including international companies, such as AB InBev, and traditional breweries including Trappist monasteries. Most beers are bought or served in bottles, rather than cans, and almost every beer has its own brand, sometimes uniquely shaped, glass.
